Rated 5 out of 5 stars

There is only one issue: After some time it gets disturbing when the toolbar appears and disappears and the browser window moves up and down. I would appreciate it so much if there were an option that the webpage stays at its position while the bookmarks bar slides over the top of the webpage.

If it's not easily doable, maybe it could be done by adding a negative offset to document.body.style.top?

This review is for a previous version of the add-on (1.21.1-signed.1-signed).
